Sensor Cable Connection
For reasons of compatibility, the expression "sensor
cable" is used in this document, although the pres-
sure reading of the SD-type gauge is normally
transmitted via the DeviceNet interface.

Operation
Caution
Caution: data transmission errors
If the gauge is operated via an RS232 interface
and the DeviceNet at the same time, data trans-
mission errors may occur.
The gauge must not be operated via an RS232
interface and the DeviceNet at the same time.
Operating Software
Before the gauge is put into operation, it has to be configured
for the DeviceNet. A configuration tool and the device specific
EDS file (Electronic Data Sheet) are required for this pur-
pose. This software can be downloaded via internet
(
→ [5]).
Node Address Setting
Set the node address (0 … 63
dec
) via the
"ADDRESS" "MSD" and "LSD" switches.
The node address is polled by the firmware
when the gauge is switched on. If the set-
ting deviates from the stored value, the
new value is taken over into the NVRAM. If
a setting higher than 63 is made, the pre-
vious node address setting remains valid.
If the MSD switch is in the "P" position, the
node address is programmable via the
DeviceNet (
→ [3]).
Data Rate Setting
By means of the "RATE" switch, the data rate can
be set to 125 ("1"), 250 ("2") or 500 kBaud ("5").
If the switch is in any of the "P" positions, the data
rate is programmable via the DeviceNet (
→ [3]).
The admissible data rate depends on several factors
(system parameters, cable lengths etc.) (
→ [8]).

Green
Normal operation
Red
Non recoverable error
"STATUS NET" (network status):
Light status
Meaning
Dark
Gauge not online:
– Selftest not yet concluded
– No supply,
→ "STATUS MOD" light
Flashing green
Gauge online but no connection:
– Selftest concluded, but no connection
to other nodes established
– Gauge not assigned to any master
Green
Gauge online; necessary connections
established
Flashing red
One or several input/output connections in
"timed out" status
Red
Communication error. The gauge has de-
tected an error that impedes communica-
tion via the network (e.g. two identical node
addresses (MAC ID) or "Bus-off")
